keccakf1600 loaded but keccakf1600_nif is not (Windows 10)

[seanwbren]

Hello, on a quite-fresh Windows 10 install I've run into this problem in both versions 2.0.0 and 3.0.0

iex(7)> [warn] The on_load function for module keccakf1600_nif returned:
{:error, {:load_failed, 'Failed to load NIF library c:/Users/seanw/Documents/Elixir/centraldao_umbrella/_build/dev/lib/keccakf1600/priv/keccakf1600_nif: \'The specified module could not be found.\''}}
iex(7)> :code.ensure_loaded(:keccakf1600)
iex(5)> {:module, :keccakf1600}

When running mix deps.compile I see:

===> Compiling mimerl
c_src/build_deps.sh
HEAD is now at d333521 Merge #494: Support OpenSSL versions >= 1.1 for ENABLE_OPENSSL_TESTS
./autogen.sh: line 3: autoreconf: command not found

warning: Mix compiler :make_bindings was supposed to return {:ok | :noop | :error, [diagnostic]} but it returned :error
===> Compiling keccakf1600
===> Compiling certifi

So keccakf1600 seems to compile fine even with those errors, but I'm guessing those are the problem. Any advice? This may be a windows only issue due to autoconf or automake failing?
